ROLLER BEARING.

Applicationfiled May 16, 1924. Serial No. 713,648.

To all whom it may concern Be it known that I, CHARLES H. Huorrns, acitizen of the United'States, and a resident of the city of East Orange,in the county of Essex and State of New Jersey, have invented certainnew and useful Improvements in Roller Bearings, of which the followingis a full, clear, and exact description.

The present invention relates to improvements in roller bearings, and itis the principal object of the invention to provide a bearing positivelyeliminating all end thrust and cutting of the cage rings or elements.

Another object of the invention is the provision of a roller bearing inwhichfthe liability of the discs or rings between which the rollers runbecoming rough or recessed, thus interfering with the free travel of therolling elements, is prevented.

A further object of theinvention is the provision of a roller bearingforming a unitary structure of simple and economical construction, therollers of which are made from a round blank.

A still further object of the invention is the provision of a rollerbearing, the hollow rollers of which are open at one end and have asemi-spherical or curved face at their opposite closed end.

It is furthermore also one of the objects of the present invention toprovide a roller bearing in which the rollers are arranged in their cagein such manner that their outer ends are kept spaced apart from theinner faces of the cage rings, while'their inner meeting ends aresemi-spherical or curved on their outer faces.

It is also an object of the present invention to provide a rollerbearing which is very strong, durable and inexpensive.

These and other objects of my invention and advantages thereof willbecome more fully apparent as the description proceeds, and will then bespecifically pointed out in the appended claims.

In the accompanying drawing forming a material part of this disclosure:

Figure 1 is an end elevation of a roller bearing constructed accordingto the present invention. 1

Figure 2 is a front elevation of the bearing with one of the rollersshown in section.

Figure 3 is an end elevation of a modified form of roller bearing.

Figure 4 is a front elevation of the bearing, Figure two of theoppositely disposed rollers being shown in section.

Figlure 5 is a detail front view of one of the roller studs illustratingits anchorage within oneof the cage rings which is shown in section.

Figure 6 is an end elevation of one of the hollow rollers. I

Figure 7' is a detail front elevation of one of the rollcrs,'partly insection to illustrate its interior construction.

The roller bearing comprises a cage which consists of'two non-perforatedside rings or discs 10 and 11 of suitable material and size which areconnected by a plurality of suitably spaced rods 12, the outer ends ofwhich are secured or anchored in the rings 10 and 11 in any well knownmanner as indicated at 13. Between each pair of rods 12, in the spaceleft therebetween, a pair of oppositely 7 directed studs 1-1 and 15respectively are secured with their outer ends in one of the cage rings,for instance the stud 14 is secured in ring 10 while stud 15 is securedin ring 11 or vice versa. I 8

The studs carry hollow roller elements 16 drawn from a round metalblank, and each provided with a central bore 17 'adaptedto receive thestud 15. The length of each stud 15 and of the axial bore 17 of eachroller are so selected, that the engagement of the free end of the studwith the rounded end 18 of the axial bore 17 of the roller limits theinward movement of the roller on the stud to such an extent that theouter flat bottom face of the roller is kept apart or spaced from theinner face of its respective cage ring as indicated at 19, while thesemispherically curved outer end or mantle of the roller snugly fitsagainst or engages the inner face of the opposite cage ring. The innerends of the studs 15 are suitably rounded and curved in conformity withthe curvature of the end 18 of the roller bore to allow a rotation ofthe roller around the 0 stud with the leastpossible friction; thiscurvature is clearly shown at 20, Figure 5. In the modified form ofroller bearing illustrated in Figures 3 and 4,, the cage rings or discs21 and 22 are kept in spaced relation and connected to form the cage bymeans of a suitable number of bars 23 having their outer ends anchoredin the cage rings. A plurality of studs 24 are secured with their outerends in the rings 21 and 22 whi e their inner ends are oppositelydisposed as shown in Figure 4t. The rollers used with this formiofconstruction and the studs are otherwise constructed as described above,and it 7 or spaced from the inner. faces of the rings 21 and 22 asindicated. at 2A timely. 1 The OPQi'ZltlOll: of" the and 2S respecwillbe readily understood, that the hearing may be manufactured in standardsizes and may be mounted in its place of use without. the-aid of:any'special assen'ibling means.

Itwill also be clear that instead of ar 'anging the rollers pairwisebetween each two of the connecting cage rods as illustrated, any number.ofrollers may be so. used, the main and chief object of the inventionbeing, tov keep the ends of the rollers spaced apart from thecage ringsso that either no contact is made between these parts orthe contact withoneot the rings is made witharoundect or semi-spherical highlypolishedmantle end tending! to burnish, but not to. out or otherwise:gouging the rings.

@l'ianges may be made: in'the general a-rrangement and in theconstruction. of the minor details of my invention without departingfrom the scope and spirit 0]? the same as laid down. in the appendedclaims.

Having. thus described my invention what 1 claim as new and desire toprotect-by Letters Patent is:

1. it roller' bearing: comprising acage, a plurality of studs in saidcage alternating ly disposed to: point in opposite directions, each:haying'ae semi-spherical free end, and

ahollow roller on each stud-having an axial bore of a: depth lessthanthe; length otthe stud iior keeping the fiat outer end of each roller."spaced& from the; walls of said cage tmprevent gouging,

device will be entirely clear. from the above description, and-1 it 2. Aroller bearing comprising a cage, a plurality. of oppositely disposedstuds secured: with one end in the end walls of said cage and havingtheir outer ends semis'pherically curved, a hollow roller on each studhaving an axial bore of a depth less than the length of the stud, saidbore ending in asemi-spherical part adapted to be engaged by thecorrespondingly curved end of the stud, and" means for securing thestuds in the end walls of said cage. I

3.. In a roller bearing. an inner. and. an outer ring, and a pl uralityofpairwise arranged rollers interposedbetween said rings,

the rollers ofeacli. pair pointing in, opposite directions andlthealternate ends of said rollers spaced. apart fli0111 saidrings;

at. In a roller bearing an lnner and air outer end. ring, means forconnecting. said 5. In a roller bearing twoend rings con.

nected. in. spaced relation to. form a cage, pairwise arranged.studssecured at. one end in said rings, and having. their oppositelydisposed rounded outer ends extending into said cage, a hollow roller oneach ofv said studs: having an axial bore of a depth less than thelengthot the stud. for keeping the outer flat ends of said rollerspacedapart from the-inner faces of said.- rings, an; outersemi-spherical;head on each roller adapted to engage the head oftheroller on the op:- posite stud, and means foranchoring said studs insa-idrings; I y
